Abstract
An electronradiography imaging chamber providing a visual image at the chamber suitable for direct viewing and/or copying. An imaging chamber with a first electrode on the x-ray source side, an x-ray absorber in a gap between the first electrode and an anisotropic plate, and a liquid crystal material in a second gap between the plate and a second transparent electrode, with incoming x-radiation providing a charge image on the plate at the absorber gap, with the plate transferring the charge image to the liquid crystal side and modulating the liquid crystal material to produce a visual image of the charge image, which visual image is viewable through the second electrode.
Claims13
In an electronradiography imaging chamber providing a visual image suitable for direct viewing and/or copying, the combination of:
- a first electrode;
- an anisotropic conductive plate;
- a second transparent electrode;
- means for supporting said electrodes and plate in spaced relation with a first x-ray absorber gap between said first electrode and said plate and a second liquid crystal material gap between said plate and said second electrode;
- means for connecting a power source across said electrodes;
- an x-ray absorber and electron and positive ion emitter in said first gap for producing a charge image on said plate;
- and
- a liquid crystal material in said second gap, with said charge image transmitted through said plate towards said second electrode for modulating said material producing a visual image of said charge image.
